ELMER A. BRI'IZIUS, OF ST. CHARLES, MINNESOTA.

STRAINER.

To all whom it may concern:

Be it known that I, ELMER A. BRITZIUS, a citizen of the United States, residing at St. Charles, in the county of WVinona, State of Minnesota, have invented certain new and useful Improvements in Strainers; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to strainers and paplticularly that type utilized in straining m1 r.

The object of the invention residesin the provision of a strainer of the character named in which one or more straining members may be employed, and wherein the straining members may be easily applied to or removed from the strainer to permit ready cleansing of the straining members and thus maintain the device in a sanitary condition.

A further object of the invention resides in the provision of a strainer which will be simple in construction, efficient in use and comparatively inexpensive to manufacture.

With the above and other objects in view the invention consists in the details of construction and in the arrangement and combination of parts to be hereinafter more fully described and particularly pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters of reference denote like corresponding parts in the several views in which- Figure 1 is an elevation of a strainer constructed in accordance with the invent-ion shown partly in section, and Fig. 2 a detail perspective view of the locking member .for removably securing the straining members in the device, the parts of said locking member being in the position they would occupy just previous to their movement to locking position.

Referring to the drawings the strainer is shown as comprising a sheet metal vessel or funnel 10 provided with a reduced tubular discharge throat 11. Extending inwardly of the throat 11 at a point removed from its discharge end are lugs 12. Removably seated in the discharge throat 11 is a plurality of rings 13 and confined between the adjacent ends of these rings and betwe n-the Specification of Letters Patent.

Serial No. 617,930.

upper end of the uppermost ring 13 and the lugs 12 are reticulated fabrics 1 1. The rings 13 and reticulate fabrics 14; are secured against removal from the tubular discharge throat 11 by means of a locking member A which includes a pair of arcuate jaws 15 and 16 having adjacent ends hingedly connected together as at 17 whereby said jaws may be moved to locking position against the outer face of the tubular discharge throat at the lower end of the latter. The jaw 15 has its free end provided with a reduced extension 17 terminating in a hook 18.

Secured to the free end of the jaw 16 are the inner ends of springs 19 and 20 and the outer ends of these springs are connected in a suitable manner to a locking plate 20 at a point in proximity to one end of said plate. This plate 20, when it is desired to efliect the locking of the member A, is positioned as shown in Fig. 2 so that the end thereof which is adjacent the connection of said plate with the springs 19 and 20 will bear against the hook 18. The other end of said plate 20 is then forced against the outer face of the jaw 15 which will complete the locking of the member A as will be apparent. The lower edge of each of the jaws 15 and 16 is provided with an outwardly and inwardly curved extension 21 which forms a seat for the reception of the lower end of the tubular discharge throat 11 and engages the lower end of the lowermost ring 13 and thus prevents the movement of said rings 13 and the reticulated fabrics 1 1 from their posit-ion in the tubular discharge throat 11.

From the foregoing description it will be apparent that upon the removal of the looking member A by the manipulation of the locking plate 20 the rings 13 and the reticulated fabrics 14: may be easily withdrawn from the tubular discharge throat 11 for the purpose of cleaning and when this is accomplished can be reapplied in the tubular throat with ease and facility.

What is claimed is:

A strainer comprising a vessel having a tubular discharge throat, inwardly projecting lugs formed on the inner face of the throat and removed from the discharge end thereof a plurality of rings removably fitted in said throat, reticulated fabrics confined between the adj acent ends of said rings and between the end of the uppermost ring and said lugs, and a locking member securing said rings and fabric against removal from the tubular discharge throat, said throat, one of said jaws'being provided at] its free end with a reduced extension terminating in a hook, springs secured to the free end of the other jaw, a locking plate secured to said springs at a point in proximity to one end thereof, the end of said looking plate adjacent its connection with the spring being adapted to engage the hooked terminal of the extension on the opposite jaw whereby the movement of the other end of said locking plate against the outer face of the said jaw carrying the extension will positively engage said locking plate with said hooked terminal and prevent the movement of the free ends of said jaws away from each other, and an outwardly and in- .wardly curved extension on the lower edge of each of said jaws, said extension forming a seat for the lower end of the tubular discharge throat and engaging the lower edge of the lowermost ring to lock said rings against removal from the tubular discharge throat.

In testimony whereof, I afiix my signature, in presence of two witnesses.
